Atmel family of digital temperature sensors improves system reliability, reduces system cost

15 APRIL 2011

At Embedded World Nuremberg 2011, Atmel® Corporation announced the world’s first family of high-precision digital temperature sensors with both integrated nonvolatile registers and integrated Serial EEPROM memory. This combination allows for user-configured settings to be retained across power cycles to simplify the system design, reduce processor start-up code, improve reliability, and ensure proper operation. The Atmel AT30TS750 family is ideal for consumer, industrial, computer and medical applications. Digital temperature sensors have excellent accuracy and can measure temperatures over a wide range compared to other technologies such as thermocouples, thermistors and resistive thermal devices (RTDs). Additionally, digital temperature sensors can directly control other circuits in the system to offload the requirements in the microcontroller (MCU). The new Atmel temperature sensor family integrates 2K-, 4K- and 8K-bits of Serial EEPROM memory to store system parameters and user preference data. The user can then access the EEPROM, which is fully functional and drop-in compatible with industry standard I2C serial EEPROMs. The Atmel AT30TS 750 family includes a group of five high-precision, digital temperature sensor devices that are based on the industry-standard xx75 functionality offered by a number of vendors. The inclusion of nonvolatile registers to permanently store device configuration settings offers system designers superior flexibility.
